Question

A METAL BALL OF MASS 5kg FALLS FROM HEIGHT OF 490m HOW MUCH TIME IT WILL TAKE TO REACH THE GROUND? ( g= 9.8 m/a 2)

Answer 1

Your Answer Is :✔️ ✔️

Data: Mass - 5KG

Height (s) - 490M

To find - Time(t)

Solution -

s = ut + 1/2 gt^2

490 = 0(t) + 1/2 X 9.8

490 = 0 + 4.9 (t^2)

490/4.9 = t^2

100 = t^2

t = 10

Ans. The metal ball will take 10 seconds to reach the ground.
